I recently did something retarded and cant get any of my files back from my last OS (tried to partition using a free version of magic partition)

but anyways I was forced to install a new OS and I chose windows vista beta 2

Im not sure if its vista or if its just silkroad but everytime I try to install it I get an error saying "silkroad online cannot be unzipped, zip is corrupted installation"

I tried downloading it again and the same thing came up

any remedies?

btw vista rocks!!
